Claims.

This: invention relates to apparatus for the fleshing. and. scraping of fur skins, as well as for the performance thereon of other related opera tions, such asshaving. and plucking; one of its 5 main objectsbeing to enable an operator at all times to readily control and adjust the relative positions of the operating tool and the pelt so asto produce uniform and effective results.

In most devices of this class, the skin is placed upon and. strapped to a cylindrical base, the tool being operatively movable along the surface of the skin either. by manual or mechanical means. The base is made rotatable and movable longitudinally in a direction parallel to-its axis, so as toexpose every portion of the pelt to the action of the tool; and it is also movable upwardly towards said tool to vary the pressure thereof upon the skin in accordance with the nature of the operation or with the varying conditions and characteristics of different portions of each piece of skin. These movements are generally accomplished. by the manipulation of several handles, levers and treadles,-irequently making such a device cumbersome, difficult to operate, and requiring great skill and considerable caution in getting the proper coordination between hand, foot andeye, and necessitating arare degree of steadiness to maintain, throughout each stroke of the tool, constant and unvarying pressures.

We have therefore conceived this invention to overcome these defects by producing a base capable of universal movement, adjustable by hand, and provided with means to adiustably hold it locked in a set position. during the operating stroke. Other features, objects and advantages will appear from the d rawings, and the description hereinafter given.

Referring to the drawings,

Figure 12 is a section through the slotted portion of an arm in the parallel motion linkage, taken along line 12-12 of Figure 1; and Figure 13 is a fragmentary section of Figure 12 taken along line 13-13.

In the drawings, the frame 15 has rotatably mounted thereon two shafts supported by bearings 16 and 17 respectively, the former shaft carrying the pulleys l8 and 19 and the fly wheel 20, and the latter the cam plate 21. The arm 22 of said fly wheel contains the slotted aperture 23, the walls of which have the notches or serrations 24 therein in parallel alignment with the corresponding notches 25 in the adjacent slotted aperture 26 at the terminal of the substantially horizontal tool -actuating member 27. This latter member is pivotally connected, through the bifurcated end piece 28, to the bracket 29, the upper portion of which contains the pin 30 upon which is pivotally mounted the bar 31, through its end piece 32; and the lower portion containing the pin or bolt 33 upon which is pivotally mounted the tool-carrying member 34, the tool or curved blade 35 being suitably secured thereto. It will be noted that the said bracket 29 contains the recess or opening 36, to accommodate the end piece 32 between its lateral walls.

Coextensive with bracket 29 is the extension 37 which contains the adjusting screw 38, the terminal of which is adapted for abutment with the boss 39. The combination of the member 27, the bracket 29 and the bar 31, together with their connecting parts, form a toggle the constituent parts of which are substantially in fixed relation to each other on the power or operating stroke (in the direction of the arrow, Figure 1), due to the contacting of said screw 38 and the boss 39 which holds said parts against further outward movement; but on the return stroke, the toggl is collapsible inwardly, so that should there be any wrinkles or upwardly protruding portions of the skin 4.0 contacting with the blade 35 on its return stroke, there will be no harm done to the skin, as the toggle will give and the blade will pass harmlessly over any obstacles on said skins;

The pivotally connected links 41 and 42 are of such lengths that they will coact with members 2"! and 31 to produce a motion of the tool 35 in a direction substantially parallel to the surface of the fur support or base 43, or to the axis of the cylinder of which a peripheral portion constitutes the said base 43. The said link 41 contains the 5 slotted aperture 44 the walls of which have the notches 45 therein in parallel alignment with the corresponding notches 46 in the adjacent slotted aperture 47 in the forward portion of the frame 15.

Movable within each of said slots 44 and 47 are the notch-engaging members 48 and 49 respectively, these members being shown square in cross-section and having two of their diametrically opposed lateral edges engaging oppositely positioned notches. The said members are rotatably mounted over the shank of the bolt or pin 50, the head 51 thereof and the nut 52 at the opposite extremity thereof holding the said members secured in place within the slotted apertures,-and yet not preventing the pivotal movement of the link 41 about said pin. Similarly, the notchengaging members 53 and 54 are movable within the slots 23 and 26 respectively, these members having lateral corners engageable within notches in said recesses, and being likewise pivotally mounted over a pin 55. One extremity of said pin extends through the slot 56 in the cam 21 and is operatively engageable therewith. The said notch-engaging members 53 and 54 are yieldably held against lateral movement and in place within the slotted apertures by the nut 57 and washer 58 at one end of the pin, the spacer 59 between the two said slotted apertures, and the spring 60 operating on two washers placed contiguous tothe slots 56 and 26.

Engageable with the periphery of the cam 21 is the follower 61 pivotally attached to the arm 62 which is shown integral with the hub 63 afiixed to the shaft 64 by the pin 65. The collar 66, similarly attachedto the said shaft 64 by the pin 67, contains the lug 68; the lug 69 integral with the collar. 70 which is rotatably mounted over the shaft 64,'extending outwardly opposite the lug 68 to accommodate, between said lugs, the helical spring 71. (See Figure 8.) Extending through said lugs and said spring is the bolt 72, which is held in place by the nut 73. The arm 74 (Figure 3), shown integral with the collar 70, extends downwardly, and has at the lower end thereof the slot 75, with which the pin 76 is slidably and operatively engageable, said pin extending through the bifurcated extremity 7'7 of the chuck control rod 78 which is attached to the central conical member 79 of the chuck mechanism containing the four wedges 80. The outer surfaces of said wedges are frictionally engageable with the inner walls of the cylindrical housing 81 which is mounted upon the tube 82 and upon which is afiixed the supports 83 and 84 for the base 43. Positioned over the rod 78 is the helical spring 78a, one end of which abuts against the end wall 82a of the tube 82, the other end abutting against the collar 78b afiixed to the rod 78.

Connected to the collar 63 is the lift control arm 85 which is operatively connected, by the link 86 to the cam 87 rotatably mounted on the shaft 88. (See Figure 5.) The end surface of said cam 87 is yieldably kept in frictional engagement, by the spring 92, with the contiguous end surface of the boss 89 secured to or forming an integral part of the framework of the apparatus. The said end surfaces contain complementary recesses and protruding portions, the recess of one being in engagement with the protruding portion of the other in the inoperative position of the parts, and

the two protruding portions being in engagement in their operative position. The bell-crank or lever 90 is integral with the sleeve 91 rotatably mounted over the said shaft 88, said sleeve serving also as an abutment for the spring 92.

The bracket 93 is pivotally attached to the end of the arm 94, and is surmounted over and attached to the tube 82. Another lever 95 is integral with the sleeve 96 (Figures 1 and 2) which is rotatably mounted over the shaft 97; and pivotally connected to the end of the arm 98 is the bracket 99 surmounted over and attached to the tube 82. The link 100 pivotally connects the extremities of the arms 101 and 102 of said levers.

Positioned over the fur piece 40 is the flexible band 103 (Figures 1, 3 and 7), which may be of steel, and this extends around the suitably mounted block 164, which may have a steel facing 105 on its upper surface for the protruding element 106 of cam 107. The crank handle 108 attached to this cam is also frictionally engageable with the flexible transverse member 109. The handles 110 and 111 are suitably attached to the base 43, and are adapted for actuating said base, by the operator, either in a rotary, longitudinal or vertical direction.

In the operation of this apparatus, the fur skin 40 is placed under the band 103 upon the base 43 and firmly secured thereto by turning the handle 108 (Figure 7) in a clockwise direction, causing the protruding element 106 to force the block 104 downwardly, thereby tensioning said band 103 about said skin. The frictional engagement of said cam and the surfacing 105 holds the parts in their projected position, until released by turning the handle in a counterclockwise direction. Once the skin is so set, the entire operation can be performed over the whole surface of same without shifting its position.

The shaft at bearing 16 is caused to rotate by a belt operating upon the pulleys 18 and 19, to cause the fly wheel 20 to rotate, thereby producing a reciprocating movement of the member 27. In this way the tool 35 is caused to operatively move along the surface of the skin in the direction of the arrow (Figure 1) for its operating stroke, the straight-line movement in a direction parallel to the surface of the base 43 being effected through properly designed members 31, 41 and 42, as hereinbefore stated.

The pressure applied by the tool is adjusted by the operator, and once so adjusted, is maintained by the lift control mechanism as follows: The rotation of the fly-wheel 20 is transmitted to the cam 21 through the pin 55, and the cam in turn actuates the roller 61, the arm 62, the hub 63 and the lift control arm 85. This motion is transmitted by the link 86 to the cam 87 which is caused to rotate until the protruding portions of the surfaces of parts 87 and 89 come into engagement (Figure 5); and when this occurs, the spring 92 is compressed, thereby forcing the sleeve 91 against the wall of the framework at the opposite end, to frictionally hold said sleeve and the lever 90 against movement. As the lever 90 is connected to lever 95 by the link 100, neither of these levers can move, and hence the brackets 93 and 99 are held stationary, during the operating stroke, to hold the tube 82 and consequently the entire base assembly against a lifting movement. During the return stroke, however, the depression in the cam 21 releases the follower 61 and the connected mechanism, (due to the action of spring 78a, as will be hereinafter frictional contacting with i described), thereby freeing the base from its.

locked position and permitting the tooll toireturn to its starting position,.out of engagement with the. skin. form on- -the skin, the toggle linkage will collapS as already described, to permit the. tool to pass harmlessly thereover;

It should be noted that. in. the r unlocked. position of: the parts, the operator, by graspingxthe' handles 110. and 111, can. raise: and; lower the base: at will, aslthe levers QO and 95 areid'esigned to. permit a parallel movement of? the lifting brackets 93 and 99;

Shouldthe'operator desireto controltthe blade pressure throughout the operating stroke without liavingia fixed and locked adjustment, he can remove the'pin l12" (Figure 1), and the'lift' control mechanism becomes inoperative.

The'base43. can be moved either longitudinally:orrotatab1y; by manipulating thehandles 110: and 111, pushing, pulling or rotating them;the'

housing 81' which supports" the base being rotatabl'y and slidably surmounted: over the tube 82.

In this way every portion of the skin can: be reached.

During the'operating stroke, the cam-actuated arm 62' causes the shaft 64' and the collar66 to rotate, through the pins and 67; and this movement is yieldably transmitted. through the spring- 7-1 and-lug 69th the rockerarm '14, therebyJcausing, during the operating stroke, a movement of the rod 78 in the direction of the ar row;against theactionof spring 78a (Figure 3). This-movement causesthecentral'member '79 to 4 force'the wedges 80' through the opening in the tube 82 against the inner surface of the housing 81, to frictionallyholdit against movement. Itis hence apparent that during the operating stroke, no movement of the'base is possible either in: a longitudinal or a. rotary'direction.

Althou'gh the arm 62 may move through aconsiderable distance, the arm' 7 being yieldably actuated by the spring 71, moves only until: the wedges 80 are frictionally held in place,-any

furthcn'movement of said arm 62'being talren upby saidspring. It should however, be noted'that the' return movement of the arm '74, and consequently the rod- 78, is positive, as the nut 73 lug 69- and hence on all parts immovably connected therewith, suchas the arm 74. When the roller 61' is relieved of the acts directly upon the pressureof the elevated: portion of cam 21, the

spring78a, by virtue of the'potential energy stored w-lth'in it due to the movement of the rod 7% l in the direction ofthe arrow (Figure 3), will expand, and force the rod' '78'to move towardsthe right, which motion is transmitted through the link 74 and the connectedmechanism tothe roller 61 to return it to and yieldably hold it I againstthe depressed portion of cam 21.

If it is desired to change the length of the stroke; the nut 57 isloosened and the notchengaging member 53 moved within the slot to the position which will give the desired stroke.

Thenct-ch-engaging member 54' must, however,

also be movedwithin itsslot a sufficient distance to bring the tool back to its original starting point. Inthis way the stroke can be changed without affecting the starting position; If the notches in both of said slots are in parallel'alignmerit, the said notch engaging members should be moved through the same number of notches to get the correct corresponding positions. A corresponding andsimilar adjustment must be made within the slotted apertures i4 and 47, to cor Should any folds or wrinkles rectly adapt its movement to." the changedacone ditions.

It is to be noted that the tool: 35 should: be curved, so that there will be a leadingedgedursing its operating movement, thereby. producing cleaner and more effective results,lparticuimay when the toolis a cutting or shownin Figure l, to give best results.
